if somethign were to happen and i had to do it all over again, i'd probably go with a turbo kit. stop light to stop light i normally win, but how often do you stop racing after 60 mph.

i can be frustrating getting passed up in the 1/4 right before the finish line, which is why i think i'll be spraying a 35 shot in 3rd and 4th gear soon.

i did beat a turbo'd miata (rwd) last weekend at the illegals by a 1/4 of a car. so the supercharged are victorious over turbo from time to time.

anyways turbo is more efficient, unless most of your playing will be done stop light to stop light or at autocrossing.

all in all its up to what you prefer, do what fits your driving needs the most, not what popular vote says, in the end, you'll be the one driving the car.
